Divided. and this application area May 20, 1930. Serial No. 453,966; 7 1 v v i r This invention relates to fastening devices and more particularly to cotter pms and means for automatically locking the same in position.

The principal object of the invention is the provision of new and improved means for spreading the arms of a cotter pin in applyingthe same in use,

Another object of the inventionis the provision of a new and improved cotter pin together with novel means for spreading the arms of the same laterally at right angles to the plane of the arms of the pin.

A further object of the invention is the provision of a new and improved cotter pin together with novel means for spreading the arms of the same, that is simple in construction, inexpensive to manufacture and efficient in use. 7

Other and further objects and advantages of the invention will appear from the following description taken in connection with the accompanying drawingsyin which I Fig. 1 is an elevation of a cotter pin showing the invention in position therein;

Fig. 2 is a similar view at right angles to i that .shown in Fig. 1;

' cess 16 at the outer ends of said arms.

Fig. 4 is a perspectiveview-of a modified 1 form of spreadermember Fig. 5 is a similar view of a further modified form of spreader member; 7

Fig. 6 is an elevation of a blank from which the structure shown in Fig. 5 is formed;

Fig. 7 is an elevation of a portion of a cotter pin showing a still further modified form of.

spreader member in position therein; and

Fig. 8 is a perspective view of a portion of the spreader member shown in Fig. 7.

Referring now to the drawings, the refer-. ence character 10 designates a cotter pin which may be formed in the usual manner from half round wire bent back on itself to form the eye 11 and'the arms 12 and 13. The ends of the arms 12 and 13 are provided with oppositely arranged diagonal faces 14 and 15 so arranged as to form a V-shaped reerably this recess is formed by cutting one Pref of the arms diagonally in one-direction' and the other in the-other direction as shown in end ofthe body portion when-the same-is in positionbetween the arms of the pin.

The outer end of the spreader member 18 is provided with suitable'means for engaging the inclined faces 14 and 15. .As'shown, the outer end ofl'the' body portion, 18 is provided With'an enlarged portion 23 having on one side the inclined; or diagonally arranged face 24 and on its opposite'side a corresponding inclined face .25 arranged to, extend in the opposite direction from i that of the face 124. WVhen the parts are inlassembledfirelation as shownin Fig.1 thev body portion 18 is between thearms of the pin and the in-'.

clined face 24 is in engagement with the inclined face 15, and the inclined'face'25 is in engagement with the inclinedface 14, of said HI'HIS. Y i

In use, thejpin; is inserted inan opening in a'bolt. or the like andls struck onits inner end with one or more blows of a hammer which will-cause the arms to bedistorted laterallyat right angles to the "plane of said 5 arms. The spring pressure of the arms will gripthe' bodyv portion of the Y spreader for preventing longitudinal jmovement I of the spreader during the shipment of the deviceandthe enlarged portion 23 engagingin the ll-shaped groove 16 will prevent lateral movement of the outer end of the spreader member while the bends- 21: and 22 will prevent the lateral movement of the inner-end ofthe spreadermember. The construction shown in Fig. 5 'difiers from that justldescribed in that the head or enlarged outer end; 26 of the spreader member 27 is formed from sheet metal. The blank forjfor'ming'} the spreader member .is shown 1n Fig; 6 and comprises'the lfiat', thin body portit'm the" laterally extending wings 29 and 31 on the inner end of said member. 7 The outer end of the member is providedvwith laterally extending wings 32 and 33. 7 These wings are provided withinclined edges 34 and 35. These wings are bent over on to the body portion 28, one on one side and the other on the other side.

The inclined edges 34 and 35 will correspond to the inclined edges 24 and 25 of the device described above. V

The form of construction shown n Figs.

" 7 and 8 differs from the constructionpreviously describedin that the head 36 of the 1 spreader member 37 is not provided with V inclined surfaces for engaging the corresponding inclined surfaces 14 and 15 of the cotter pin 10. In this form of construction the spreader member is madefrom a strip of metal, the inner end being formed withwings as described above and its outer end or head 36 being formed by bending the sameat right 1 angles to the body portion 38. The head 36 is adapted toengage in the V-shaped groove 16 and when the pin'is forced in an opening of a bolt or the like the head 36 will engage the inclined surfaces 1 1 and 15 and bend the arms laterally-as in the previously described construction. v V
